VIBRA'IOR HOOK.

Original Ho: 1,447,ee4,

Our, invention relates to hooks to which a vibrator mechanism isattached. a

The object of our invention is to provide a hook-or similar mechanismwith an efficient means for setting up vibrations in these hooks orother similar mechanisms for the purpose of removing sand, dirt, etc.,from objects connected to these hooks, etc.

In many instances it is necessary thatsand, or dirt, or other matter beremoved from the inside or outside of. boxes, flasks, etc., but suchmatter usually adheres to the walls of these boxes, etc., andrequires'considerableefl'ort. and time 'for its removal. In foundryflasks for instance, the sand adheres to the walls of the flasks after amold is cast. It requires considerable time and effort to remove thissand by manual scraping and pounding on the flask with a mallet or othertool and, quite frequently, the flask is broken thereby.

The present invention aims to remove the sand from these flasks as wellas other objects which are encumbered in a similar manner, by setting upvibrations in the material of a hook or other means upon which theflasks, etc., are suspended or supported and thereb shake out all sand,etc., without manna effort and in much less time than such operationcould be done by manual means.

An apparatus to attain the above object .is shown in the accompanyingdrawing and described in this specification, but it is understood thatvarious changes and modifications maybe made within the spirit of thisinvention and without sacrificing any of the advantages contained in theappended claims.

The accompanying drawingillustrates a vibrator hook mechanism in asingle 'perspective view, partly broken away to show the vibratormechanism clearly. v This hook mechanism comprisesthe bail A and thehooks B.

The bail A, made of suitable mate'rial, has the arms 10 and 11, andthecylindrical portion 12 substantially at right angles to these arms,and the loop 13 which is adapted to be engaged by a crane hook, or othermeans.

This portion 12 has the counterbore 14 which is open, at the bottomwhere it is dated March 6, 1923, Serial No. 500,194, filed-September 12,1921. Application for reissue filed September 5, 1824. Serial No.738,176.

threaded as shown, but which is closed at the top by the wall 15integral with the portion 12 of the bail A. This wall 15 has the opening16 into which the anvil block 17 is driven. This portion 12 further hasthe exhaust ports 18 and 19, and the inlet chamber 20, and the inletport 21 opening into the chamber 20, and the boss 22 into which thesupply pipe 23 is screwed. A rubber hose or other means may be attachedto the pipe 23 for connection with a source of fiuid pressure supply.

Inside of this counterbore 14 is 'the sleeve 24 which is renewable whenworn and is provided with the exhaust ports 25 and 26 corres onding tothe exhaust ports 18 and 19 and with the inlet ports 27 and 28 properlyspaced and opening into the chamber 20.

This proper spacing of the inlet ports 2' T and 28 will appearhereinafter. r

This sleeve 24 may be renewed when worn so that the bail A itself is notaffected by wear and this sleeve also establishes a wall between themain bore of the cylinder and the chamber 20 so that the entering" fluidpressure can not reach the inside of the sleeve 24 except through theinlet ports 27 and 28.

The plug 29 is screwed into the threaded dnd-of'the bore 14 and has theroundedouter end 30 and the anvil boss 31- projectinga short distanceoutside of the main body of the plug 29.

This anvil boss should be suitably hardened to revent up setting, butshould not be so brittle that pieces may break off and interfere withthe action of the vibrator.

Through the lower portion of the cylindrical portion 12 and properlyspaced in relation to the round end 30 of the plug 29 is the rectangularopening 32 to receive the taper key 33; This key 33 is so located'thatthe upper surface thereof bears against the round end 30 of the plug 29while the bottom surface thereof :rests firmly upon the'material of thebail A.

The taper construction of this key, aidedby the nut 34 thereon,establishes a firm connection and. a solid'joint between the plug 29 andthe material of-the bail A, and such oint can be taken up in case theelements 31 and the anvil block 17 Wear and can be held ti ht by meansof the nut 34 which is not affected by the action of the vibratormechanism since it acts substantially at right angles thereto and thetaper of the key need not be sufliciently great to exert any appreciableforce against this nut. c

It is not necessary that the plug 29 be threaded into the opening 14 andany suitable means of closing the lower end of this opening may beemployed.

It is important however, whatever mechanism is employed, that the block.17 and the plug 29 bear directly upon the material of the bail A sothat the vibrator mechanism acts directly against the material of thebail A and creates vibrations therein.

Inside of the sleeve 24 is the plunger 35 which is provided with theanvil projections 36 and 37 and with the grooves 38 and 39,. suitably saced as will appear hereinafter, and wit the holes 40 and 41 openinginto the grooves 38 and-39 respectively.

The anvil projections 36 and 37, as well as the plunger as a whole, areproperly hardened to mitigate wear of the plunger proper as well asupsetting of the'projections 36 and 37, but

a not be sufliciently brittle to chip or permit pieces to break ofl andinterfere with the action of the vibrator mechanism.

The hooks B shown have. the openings 43, preferably rounded at the topas shown, b which they are suspended on the ends of the bail A and areheld therein suitable position by the pins 44, the rounding of the topsof the openings43 ermits the hooks to rock on the arms 10 and 11 of thebail A.

The lower ends of these hooks are adapted to engage the projections'45of the flask 46 shown in dot and dash lines. These lower ends may bemodified to engage other articles and the upper ends may be modified forrigid or other connection to the bail.

The operation of this apparatus is as follows:

Fluid pressure, such as compressed air for instance, is admitted throughthe pipe 23 into the chamber 20. The plunger is now in its lowestposition, as shown in the drawing, due to its own weight when thevibrator mechanism is at rest. Fluid pressure now flows from the chamber20, through the port 28, into the; groove 39, through the hole 41, andinto the space 47. At the same time, the space 48 is in communicationwith the open air through the hole 40, the groove 38,

and the exhaust ports 25 and 18. The exhaust port 26 is now closed bythe plunger.

The fluid pressure in the space 47 now forces the the block 1 at whichstage the groove 38 registers with the inlet port 27,- admitting fluidpressure to the space 48 through the space 47 through the theseprojections should the apparatus,

lunger upward until it strikes until it strikes the plug 29; during thisstroke, the fluid pressure escapes from the hole 41, the groove 39, andthe ports 26 and 19. This operation is repeated and continues to repeatautomatically as long as fluid pressure is supplied to the chamber 26'.The relative spacing. of the grooves 38 and 39 and the ports 25, 26, 27and 28 should be so arranged that the plunger opens and closes theseports at the proper time lVhen the plunger operates as set forth andstrikes the anvils sharp vibrations are set up or created in the anvilsand are transmitted directly to the material of the bail A and fromthere to the hooks, B and to the flask 46. These vibrations in the flask46 cause all sand, etc, to be loosened and removed therefrom in muchless time than manual effort could do so.

It will be seenthat this apparatus is efiicient since it removes sand,etc. efiectively and quickly, has few parts, the parts subject to wearcan be adjusted and renewed, and the vibrations created are transmitteddirectly to the article operated upon.
